Backups have two distinct purposes. The primary purpose is to recover data as a reaction to data loss, be it by data deletion or corrupted data. Data loss is a very common experience of computer users. 67% of internet users have suffered serious data loss.[2] The secondary purpose of backups is to recover data from a historical period of time within the constraints of a user-defined data retention policy, typically configured within a backup application for how long copies of data are required. Though backups popularly represent a simple form of disaster recovery, and should be part of a disaster recovery plan, by themselves, backups should not alone be considered disaster recovery. [3] Not all backup systems and/or backup applications are able to reconstitute a computer system, or in turn other complex configurations such as a computer cluster, active directoryservers, or a database server, by restoring only data from a backup.
